Prevention

• Importance of Better Storage Practices– Small Kids: Unintentional– Older Adults: Self-harm – Less effective for Assaults and Adult Unintentional

• Limiting Access to Firearms for Those with a History of Violence– Potentially effective for Assaults & Partner violence – Hard to implement at current time

• Limiting Access to Firearms universally – Hard to implement at current time

• Behavior change for Firearm owners– Always hard to implement effective behavioral interventions on a population

basis

Recommendations

• Think of Firearm-Related Injury as a Public Health Problem

• Monitor the Issue in your Region on an Ongoing Basis

• Engage Key Stakeholders in your Area and Provide Them with Data

– Owners, retailers
